Troubleshooting Checklist
Routine maintenance to this openGear product is not required. In the event of problems with your
UDC-8625A series card, the following basic troubleshooting checklist may help identify the
source of the problem. If the frame still does not appear to be working properly after checking all
possible causes, please contact your openGear products distributor, or the Technical Support
department at the numbers listed under the “
Contact Us ” section.
1. Visual Review — Performing a quick visual check may reveal many problems, such as
connectors not properly seated or loose cables. Check the card, the frame, and any
associated peripheral equipment for signs of trouble.
2. Power Check — Check the power indicator LED on the distribution frame front panel
for the presence of power. If the power LED is not illuminated, verify that the power
cable is connected to a power source and that power is available at the power main.
Confirm that the power supplies are fully seated in their slots. If the power LED is still
not illuminated, replace the power supply with one that is verified to work.
3. Reference Signal Status — Verify that the reference (blackburst or tri-level) is supplied
on one of the available reference inputs. Check the Reference Status field in the Signal
tab in DashBoard.
4. Input Signal Status — Verify that source equipment is operating correctly and that a
valid signal is being supplied.
5. Output Signal Path — Verify that destination equipment is operating correctly and
receiving a valid signal.
6. Unit Exchange — Exchanging a suspect unit with a unit that is known to be working
correctly is an efficient method for localizing problems to individual units.
7. Re-load the Factory Defaults — If the card appears to be working and reports no
errors, but is not generating an active picture or outputs black, restoring the default
factory configuration may fix the problem. Refer to the section “
Loading the Factory
Defaults ” on page 3-16 for information.
